Covering the whole development process for the global biotechnology industry

Bioprocessing begins upstream, most often with culturing of animal or microbial cells in a range of vessel types (such as bags or stirred tanks) using different controlled feeding, aerating, and process strategies.

Beginning with harvest of material from a bioreactor, downstream processing removes or reduces contaminants to acceptable levels through several steps that typically include centrifugation, filtration, and/or chromatographic technologies.

Drug products combine active pharmaceutical ingredients with excipients in a final formulation for delivery to patients in liquid or lyophilized (freeze-dried) packaged forms — with the latter requiring reconstitution in the clinical setting.

Many technologies are used to characterize biological products, manufacturing processes, and raw materials. The number of options and applications is growing every day — with quality by design (QbD) giving impetus to this expansion.

Even as it matures, the biopharmaceutical industry is still a highly entrepreneurial one. Partnerships of many kinds — from outsourcing to licensing agreements to consultancies — help companies navigate this increasingly global business environment.

Pre-Clinical and Clinical Trials

The future success of biopharmaceutical businesses will depend at least partly on their ability to create meaningful brand experiences from the start of a drug program. By “brand,” I don’t mean logos and taglines. I’m talking about meaningfully unique experiences that directly affect clinical and patient needs — specifically, to address the growing demand for self-administered injectable therapeutics. Whether you are a biosimilar developer trying to carve out differentiated value or a market leader looking at your patent protection in…

The drug development landscape is awash with candidates that have shown enormous promise and efficacy in preclinical models but failed when administered to clinical trial subjects. Although such failures occur for different reasons, one of the most pervasive causes is the inability of preclinical models to recapitulate human physiology accurately. Despite advances with both in vitro and in vivo models, improving those toward a more accurate avatar of the human physiological process remains a challenge. Central to that effort will…

Rapidly increasing use of monoclonal antibodies (MAbs) in the treatment of neoplastic, autoimmune, and inflammatory diseases has led to a dramatic increase in hypersensitivity reactions worldwide, complicating the use of MAbs as first-line therapies and limiting patient survival and quality of life (1). The origins of anaphylaxis are not well understood, though its mechanism is fairly straightforward (Figure 1). It is usually attributed to some undefined intrinsic property or properties of a biotherapeutic — despite the fact that biotherapeutic formulations…

Biosimilars have become common on pharmacy shelves in Europe. The first biosimilar product — Sandoz’s Omnitrope version of Lilly’s Humatrope (somatropin) — was approved by the European Medicines Agency (EMA) in 2006. In the decade that followed, more than 20 biosimilars have gained regulatory approval in Europe. The first biosimilar monoclonal antibodies (MAbs) — comparators to Janssen’s Remicade (infliximab) — were approved in 2013. The pace of approvals in the United States has been much slower. The US Food and…

During the Biotech Week in Boston this past October, I had a chance to talk with David DiGiusto (Stanford University) about his work toward advancing bioprocessing and cell therapy development. I asked him to comment on points from his keynote presentation about how academic research groups can sustainably cycle assets into the biopharmaceutical pipeline. University research departments have long made innovative technologies available for commercial licensing. But in the excerpt below, he details ways in which such groups are further…

Regenerative medicine includes both cell and gene therapies. Currently 672 regenerative medicine companies operate around the world, and 20 products have been approved by the US Food and Drug Administration (FDA). Of 631 ongoing clinical trials by the end of 2015 (1), over 40% are in oncology, followed in prominence by cardiovascular and infectious diseases. Here I focus on gene and cell therapy bioprocessing in which the final products delivered to patients are cells. Cell therapies are either autologous (derived…

Continued clinical efficacy demonstrations of cell-based immunotherapies (iTx) such as chimeric antigen receptor T cell (CAR-T) therapies has made the prospect increasingly likely of an immunotherapy product achieving conditional market authorization in the short term. For example, Novartis and the University of Pennsylvania’s lead candidate (CTL019) for treating a range of hematological malignancies received breakthrough status from the US Food and Drug Administration (FDA) in 2014, permitting access to an expedited drug development pathway for high unmet medical needs (1).…

A clinical supply chain fulfills perfectly all four characteristics of what Packowski describes as a “VUCA” (volatility, uncertainty, complexity, and ambiguity) world (1). In commercial markets, supply chains depend predominantly on consumer orders. For global drug development programs, both investigators and patients can be considered end consumers. The international journey of a specific investigational medicinal product (IMP) includes all of the following: global sourcing of comparators, manufacturing, storage, distribution, site/patient (consumer) management, and return and destruction of the IMP. Application…

Cell therapy is an emerging pillar in healthcare with the potential to provide curative solutions to a wide range of indications. The biological complexities through which cell technologies exert their clinical impact (especially those used in immunotherapies for cancer) provide opportunities for novel modes of immune regulation, cell targeting, and payload delivery. Cells also can serve as vehicles for genetic content, which the gene therapy industry is now investigating. Since early 2004, Invetech has worked with organizations dedicated to cell…

Accelerating the commercialization of promising new cancer treatments relies on ensuring that patients — individually and collectively — are actively involved throughout research and drug development. This was the consensus of leading scientists, advocates, and government officials meeting in Washington, DC, at the first national policy forum convened by the Cancer Innovation Coalition (CIC). A collaboration of cancer stakeholder organizations and others working through a national campaign called Project Innovation — which is spearheaded by National Patient Advocate Foundation (NPAF)…
